5 micrograms is equal to 0.005 milligrams.
To convert micrograms to milligrams, you divide the number of micrograms by 1,000 because one milligram contains 1,000 micrograms. So, 5 micrograms divided by 1,000 gives 0.005 milligrams.

Conversion Formula
The formula to convert micrograms (µg) to milligrams (mg) is:
milligrams = micrograms ÷ 1000
This works because one milligram equals exactly 1,000 micrograms. So to find how many milligrams a certain number of micrograms is, dividing by 1,000 scales the smaller unit into the larger one. For example, if you have 5 micrograms:
5 µg ÷ 1000 = 0.005 mg
Dividing by 1,000 moves the decimal point three places to the left, converting the value correctly from micrograms to milligrams.
Conversion Example
-
Convert 250 micrograms to milligrams:
- Start with 250 µg.
- Divide 250 by 1000: 250 ÷ 1000 = 0.25.
- Result: 250 µg equals 0.25 mg.
-
Convert 1,200 micrograms to milligrams:
- Begin with 1,200 µg.
- Divide by 1000: 1200 ÷ 1000 = 1.2.
- So, 1,200 µg equals 1.2 mg.
-
Convert 0.5 micrograms to milligrams:
- Take 0.5 µg.
- Divide 0.5 by 1000: 0.5 ÷ 1000 = 0.0005.
- Therefore, 0.5 µg equals 0.0005 mg.
-
Convert 999 micrograms to milligrams:
- Start with 999 µg.
- Divide by 1000: 999 ÷ 1000 = 0.999.
- Result: 999 µg equals 0.999 mg.

Conversion Definitions
Micrograms: A microgram (symbol µg) is a unit of mass in the metric system equal to one millionth of a gram, or 0.000001 grams. It is often used to measure very small quantities, such as vitamins or medication doses, where precision is required at tiny scales.
Milligrams: A milligram (symbol mg) is a metric mass unit equal to one thousandth of a gram, or 0.001 grams. It is commonly used in medicine, chemistry, and science to measure substances in amounts larger than micrograms but smaller than grams.
Conversion FAQs
Can negative microgram values be converted to milligrams?
Yes, negative microgram values can be converted to milligrams by the same division method. Negative values might represent a deficit or a decrease in quantity. For example, -10 µg equals -0.01 mg, keeping the sign consistent after conversion.
Why do I divide by 1000 instead of multiply when converting micrograms to milligrams?
Micrograms are smaller units compared to milligrams. Since 1 milligram equals 1000 micrograms, converting micrograms to milligrams means scaling down the number, so you divide by 1000, which shifts the decimal point leftwards, reducing the value in terms of milligrams.
Is the conversion factor always constant for micrograms to milligrams?
Yes, the conversion factor between micrograms and milligrams is constant because both are metric units based on powers of ten. The fixed ratio of 1000 micrograms per 1 milligram does not change regardless of context or substance measured.
Can I convert micrograms to milligrams in my head?
Yes, converting micrograms to milligrams can be done mentally by moving the decimal point three places to the left. For example, 5000 µg becomes 5 mg. This quick mental math works for any microgram value.
Are micrograms and milligrams used for the same substances?
They can be used for the same substances but at different scales. Micrograms measure very tiny amounts, such as trace elements or potent drugs, while milligrams measure larger quantities. Choice depends on precision required in measurement.
